IMPROVEMENT IN HUBS FOR VEHlC'LE-WHEELS.

` Speciiication forming part of Letters Patent No. 128,794, dated July 9, 1872.

To all whom it may concern;

Be it known that I, CHARLEs G. GRAY, of Ansonia, in the county of New Haven and State of Connecticut, have invented a new Improvement in Carriage-Hubs; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marlied thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this speciiication, and represents in Figure 1, a side view; Fig. 2, alongitudinal central section; Fig. 3, a transverse section on line :c Fig. 4, a transverse section on line y y; and in Fig. 5, a transverse section on line z '2.

rI.`his invention relates to an improvement in metal carriage-hubs, the object being to construct the hub with a metal center to receive the spokes, with a wood lling to sustain the box, and, with the bands, a part of the shell which forms the exterior of the hub 5 and the invention consists of a metal shell, forming the mortises for the spokes and the bands complete in one and the same piece, combined with a wood iilling to sustain the box, all as more fully hereinafter described.

A is a metal shell, forming the exterior of the hub', and with the band C cast in the same piece. At the center two iianges, a, are formed around the shell, and between these bars d are arranged, as seen in Figs. l, 2, and 3, between which are the mortises for the spokes, these bars being formed below the edge ofthe iianges a. The shell, band, and bars d are all cast in one and the same piece, and the flanges extend inward, as denoted in Fig. 2, to form a center to receive the box D 5 thus a chamber is formed between the central or mortised portion and each end. These chambers are constructed with sharp-edged inwardly-projecting iianges f, as seen in Figs. 4 and 5, and into these blocks of wood F are driven to lill the space within the hub, or nearly so, and driven onto the sharpedged anges. These blocks are,by the said flanges, held rmly in position, and through the center of these blocks the box D is inserted, and secured therein in substantially the usual manner.V A

The shell of the hub may be made very light, as denoted in Fig. 2, and, combining therewith the bands B and C, all loosening of the bands is avoided; and by the use of the wood filling the box is set in the usual manner; thus I combine all the advantages of a solid metal or a solid wood hub.

I cla-im as my invention- The herein-describedhub for carriage-wheels, consisting of the shell A, provided at its center with the two anges a, and these connected by bars d, toform the mortises to receive the spokes, the internal anges or ribs f, and with the bands B C, all cast in one and the same piece, and filled with the wood blocks F F, in the manner described, to support the box D.
